scum. (01. 229-21) tively small compact space and readily unfolded 10 and adjusted foruse forthe reception of the bottles to enable the latter to be stored or-carried from place to place with a minimum liability of breakage of the bottles.

Another object is to provide the bottom of the carton with an upright extension adapted to extend across and closely adjacent the inner face of one side of the tubular body of the carton and to provide the upper ends of said extension and op-' posite side of the tubular body with cover flaps having handles by which the carton may be carried and thereby to establish a connection between the handles andbottom of the carton'to-better resist the weight of the filled bottles resting upon said bottom when the carton is carried from place to place. I

Another object is to arrange the handles of the cover flaps so as to interlock one with the other when the upper ends of said flaps are brought together for holding them. in their closed positions and also to aiford a rounding gripping surface on the lower side of the handle for convenience of carrying the carton.

A further object is to provide the upright extension with inwardly projecting partitions arranged in uniformly spaced relation to each other and to the opposite upright edges of the carton to form a series of compartments for the reception of thebottles and prevention of their contact one with the other and thereby to reduce the liability of breakage of the bottles in storage or transportation.

Other objects and uses relating to specific parts of the carton and blank for forming the same will 45 be brought out in the following description.

plane. of line 1-1,

Figure 815 a plan of the blank for forming the carton shown in Figure 6.

As illustrated, the carton comprises a substantially rectangular tubular body I adapted to stand in-an upright position and preferably elongated laterally in one direction to form opposite relatively broad flat upright sides 2 and 2' and narrower upright sides 3 and 3' The lower end of the tubular body I is normally closed 1 by a bottom wall 4 which is, integrally united at. 5 to the lower end of one of the flat sides as 2 of the tubular body and has its opadapted to project inwardly therefrom in parallel spaced relation uniform'distances apart from each other and from the upright side walls 3 and 3' to form a series of, in this instance three, compartments 8 for receiving the bottles as a and holding the latter outof contact with each other to reduce the liability of breakage.

The junctions or folding lines 5 and 5' between the bottom 4 and upright side 2 and extension 6 are preferably scored asindicated in the blank,

Figure 5, to facilitate the folding operation without liability of breaking the fabric and'also to assure the folding at. right-angles to the sides of the tubular body, it being understood that the bottom portion 4 is of substantially the same cross-sectional area as that of the interior of said tubular body The partitions l are of similar length but considerably less than that of the extension 6 and are preferably located near the bottom portion 4 so as to leave considerable space above the partitionsto facilitate the. entry of the bottles as a between them from the top downwardly until the bottles rest'upon the bottom lines in Figure 2.

4, as shown by dotted The partitions I are integrally united at l-to the extension 6 and are adapted to extend therefrom across the major portion of the interior width of the tubular body I, said wings being formed by cutting through the blank along three sides of each wing, as shown at M in Figure 5, in which the junctions of the inner edges of the wings with the blank are shown by dotted score lines 8 representing the junctions of the wings with said extension, it being understood that the folding lines s of the wings are parallel with each other so that when the latter are folded inwardly they will be disposed in parallel planes at right angles to the extension.

The junctionsof the upright sides- 2 and 2' with the broader upright side 2 are scored along parallel lines ll, Figure 5, andin like manner the junction of the narrower broader side 2 5, to facilitate the folding and sides of the tubular body.

The portion of the blank forming the side 2' of the tubular body is provided with a relatively narrow lengthwise adhesive ilap |2 scored at ll along its junction with the part I for folding purposes and adapted to be adhesively secured to the inner face of the'u'pright side 3' of the tubular body to complete the tube.

The upper ends. of the side member 2 and extension 6 are provided with similar cover flaps II and I! having handle flaps I and ii cut therefrom to form hand holes or openings l'l andll'.

The junction of the cover flap It with the side 2 of the tubular body is scored transversely as indicated by the dottedline II in Figure 5, and in like manner'the junction of the cover flap it on the upper end of the extension I is scored transversely as indicated by dotted lines ll;

The cover flaps l5 and I! extend upwardly equal distances beyond their a respective hand unfolding of the openings l1 and i1 and are scored transversely,

at their junctions with their respective handle flaps as indicated by dotted lines I! and I9, Figure 5, to form portions 22 and 2'' of the cover flaps l5 and |5' respectively;

The lower and upper ends of the narrower upright sides 3 and 2' of the tubular body are provided with similar relatively short extension tabs 2| integrally united theretoand scored alon their junctions'with their respective sides 3 and 3' as indicated by dotted lines 22, Figure 5, to enable said extensiontabs to be folded inwardly at right angles tosaid sides.

These tabs are of substantially the same width and length as the width of the interior of the tubular body across the narrower portion thereof except that the outer corners thereof are cut away diagonally at 23' to facilitate the inward bending thereof between the opposite broader upright sides of the tubular body, it being understood that the tabs 2| will be separated by a slit 24 from the adjacent portions of the bottom I and cover flap I! to enable them to be folded inwardly'along their respective score lines 22.

The handle flaps I6 and iiare'somewhat similar except that the flap I6 is provided with relatively short end extensions Ill" for interlocking engagement with the end walls of the opening I! in the flap i5 whenthe flap ll'is inserted through the opening l1. g

When forming the cari on from the blank shown in Figure 5, the portion 2' and its extension flaps 2| will be folded along the score line to a position at right angles to the side porupright side 2 with the is scored along the line l2, Figure tion 2 after which the side portion 2 with its end flaps 2| will be similarly foldedalong its junction line H to a position at right-angles with the side 2 in the same direction as the previously folded side 2'.

The side portion 2' will then be folded along the score line |2 to a position parallel with the side 2 after which the adhesive flap l3 will be folded inside of and against the previously folded side 3' and adhesively secured thereto, thus completing the tubular bodv, following which the extension tabs 2| adjacent the bottom portion 4 will be folded inwardly at right angles to their respective sides 3 and 3'.

The free end of the extension 6 will then be inserted into the interior of the tubular body along and closely adjacent the inner face of 'the side 2 of said tubular body and across the ad- '-.jacent edges of the then inwardly folded extension tabs 2| until the bottom portion 4 rests against the lower faces of the extension tabs at right angles to the sides 2 and 2', thus closing the open lower end of the tubular body and to- 'gether with the extension tabs 2| forming the bottom thereof and at the same time causing the cover flap II to extend above the tubular body in opposed relation to the cover flap ii on upper end of the side portion 2. p

when the extension I is adjusted in the mannor just described and it is desired to place the bottles 11 therein, the partition flaps I may be unfolded inwardly at right angles to the extension I to form the compartments 8- into which the bottles a may then be placed from the top downwardly. I 1 v The extension tabs 2| adjacent the upper cover flap I! may thenbe folded inwardly at right angles to the adjacent sides 3 and 3 ready for closing the cover flaps i5 and I5.

The upper ends-of the cover flaps are then brought together andthe handle flap it of the cover flap I5 is then inserted through the opening ll of thecover flap i5 and folded upwardly to form a rounding hand-engaging surface m, thereby causing the end lugs l6" of the handle flap I6 to engage the outer surface of the cover flap It to hold both fiapsin anupwardly convergent closed position and at the same time causing the handle flap I6 to fold upwardly against the inner face of the portion 20 of the flap I! as shown more clearly in Figure 2.

The carton with the bottles or other articles therein may then be carried from place to place by one'hand passing through the openingsil and H and engaging the rounded surface m of the handle flap l6, thereby holding both cover flaps in their closed positions and transmitting the load of the bottles upon the bottom 4 to the side 2 and extension 6 to prevent accidental displacement of said bottom under load.

When the carton is not in use, thehandle flap it may be unfolded and released from engagethe ment with the cover flap' I! after which the par- It is evident, however, that the tubular body may be folded flatwise in the opposite direction and the extension 5 folded flatwise upon the outer surface of the side 2' if desire It is now evident that when the carton is unfolded and adjusted for use with the bottles therein, the latter will be protected against contact one with the other by the interposed partitions I, thus provlding'a convenient and safe means for conveying a plurality of. bottles from one place to another without liability of breakage. a

On the other hand, when the cartonis not in use, a large number of them may be folded and stored in relatively small compact space, thus greatly reducing the cost of transportation.

The construction shown in Figures 6 to 8 inclusive is quite similar to that shown in Figures 1 to 5 inclusive except that it is adapted to be used as a display stand for the bottle products and for this purpose the extension as I corresponding to the extension 8, Figure 5, is provided with a medial score line as I I" midway between the score lines 5' and II to form adjacent panels 8" and 8" so that when the blank is folded to form the carton, the parts 6" and I' will form one side of the box opposite the side 2, the folded position of the various parts of the carton being shown partially by full lines and partially by dotted lines in Figure '1.

The panel or portion 8" is provided with integral folding partitions similar to but somewhat shorter than the partitions I in that they are arranged wholly between the score lines I and i8", astshown more clearly in Figures 7 and 8.

Another diiierence-of this construction over that shown in Figures 1 to 5 inclusive is that the extension or portion as I" of the blank for forming the inner portion of one of the upright sides of the carton is approximately one half the vertical height of that shown in Figures 1 to 5 inclusive so that when the various parts are folded to form the carton with the adhesive flap as i3 folded along the score line as M and adhesively secured to the opposite upright side as 3, it will leave an opening as b above the panel as 6" of about one half the vertical height of the main body of the carton, as shown more clearly in Figures 6 and 7.

The outer edges of the opposite narrower upright sides 3 and 3' are provided with relatively narrow flanges 2' of about the same vertical height as the portion 2" and, therefore, of about one half the vertical height of the upright side 2, said flanges being integrally united to their respective side portions I and 3' and adapted to fold inwardly toward each other along score lines l2, one of which forms a continuation of the score line l2, while the other forms a continuation of the outer edge of the part I, as shown more clearly in Figures 6 and 8.

Aside from the structural diiferences pointed out, the construction shown in Figures 6 to 8 inclusive is-similar to that shown in Figures 1 to 5 inclusive and the manner of folding the various parts to form the complete carton is also similar to that previously described.

For example, the parts I and I will first be folded in the same direction along the line H to positions at substantially right angles to the side portion 2 after which the portion 2" will be folded along the score line I2 and its adhesive portion l3 will be adhesively secured to the free edge of the portion 8' in overlapping relation thereto, thus holding the narrower side portions 3 and 3 in parallel relation to each other and to the upright side portion 2 with the flanges 2' projecting inwardly toward eachother, as shown in Figures 6 and 'l.

The extension tabs 2! in alinement with the previously explained in connection with the structure shown in Figures 1 to 5 inclusive.

On the other hand, if the carton is to be used fordisplaying the bottles as 0 contained therein,-

the panel portion 6" will be folded outwardly and downwardly along the score line ll" while the portion II will be folded inwardly along the score line I! afterwhich' the portion 20 on'the outer end of the extension 6 'will be inserted from the bottom upwardly across the lower edge of the portion 2" and between said portion and the portions 5", as shown in Figure 7, thus bringing the portion I! at the bottom in a plane inclined upwardly and outwardly from the bottom 4 of the carton for holding the portion 6' in an outwardly and downwardly inclined position.

Under these conditions the upper portions of the bottles a will be readily visible through the opening b while the panel 8" may be used for advertising purposes.

Otherwise, the folding operation to form the carton is quite similar to that described for the construction shown in Figures 1 to 5 inclusive, it being understood that the partitions as I will have previously been unfolded inwardly at substantially right angles to the part 8" to form the desired compartments for the reception of the bottles and for holding them in spaced relation against contact one with the other.
